The disclosure describes HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Disclosed are CMV vectors that lack active UL128, UL130, UL146 and UL147 proteins that may also comprise one or more microRNA regulatory elements (MRE) that restrict expression of the CMV. Immunization with the disclosed CMV vectors allow selection of different CD8+ T cell responsesCD8+ T cells restricted by MHC-Ia, MHC-II, or by MHC-E.

The present invention relates to a polypeptide that includes at least one mutation in the fusion loop 1 region and/or in the fusion loop 2 region and/or in the furin-like cleavage site of a human cytomegalovirus gB polypeptide. In one embodiment, the polypeptide undergoes a structural conformation change in response to pH change.

Disclosed are CMV vectors that lack active UL128, UL130, UL146 and UL147 proteins that may also comprise one or more microRNA regulatory elements (MRE) that restrict expression of the CMV. Immunization with the disclosed CMV vectors allow selection of different CD8+ T cell responsesCD8+ T cells restricted by MHC-Ia, MHC-II, or by MHC-E.

Provided are antigenic compositions and uses thereof that include at least two human herpesvirus (HHV) polypeptides involved in mediating HHV binding, fusion, and entry into host cells, such as gp350, gH, gL, and gB, or nucleic acids encoding the polypeptides. The two HHV polypeptides comprise any combination of: a gB polypeptide; a gp350 polypeptide; a gL polypeptide; and a gH polypeptide, and optionally any one or more of the following polypeptides: gp42, gM, gN, gI, gC, gE, gD, ORF68, BMRF-2, BDLF2, UL128, UL130, UL131A, and gpK8.1. Also disclosed are methods of inducing an immune response or treating or preventing an HHV infection in a subject by administering to the subject at least two of the HHV polypeptides or nucleic acid(s) encoding the same. Methods of passively transferring immunity using high-titer anti-HHV antibodies or immune cells are also disclosed.

The disclosure describes HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

The disclosure relates to HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

The present disclosure is in the field of genome engineering, particularly targeted integration of a functional SCID-related genes (e.g., IL2RG, RAG1 and/or RAG2 gene) into an IL2RG gene of a cell for provision of proteins lacking or deficient in SCID.

The present disclosure provides cytomegalovirus vectors encoding fusion proteins comprising Mycobacterium tuberculosis (Mtb) antigens, nucleic acid molecules encoding the same, cytomegalovirus vectors comprising nucleic acid molecules, compositions comprising the same, and methods of eliciting an immune response against tuberculosis.

The disclosure relates to HCMV ribonucleic acid (RNA) vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.
